Simplified graphical analysis of multiple data series

ABSTRACT

Provided are a computer implemented method, computer program product, and system for presenting information about multiple data series. The multiple data series are obtained. A main graphing area with a graph showing one or more of the obtained data series, an active process execution metrics area with information about the one or more obtained data series shown in the graph, and an available process execution metrics area with one or more thumbnail views of one or more of the obtained data series available for selection to be shown in the graph are displayed.

BACKGROUND

Embodiments of the invention relate to simplified graphical analysis of multiple data series.

Extract, Transformation and Load (ETL) processes are often executed on a repeating basis, where a particular ETL process is executed in a runtime environment, which is shared with many other system resource-intensive activities. Given varying system load, the ETL user may want to monitor variances across a range of ETL process runtime metrics (i.e., “data series” in graphing terms) to identify performance problems or bottlenecks caused by overloaded system resources and/or by other causes.

Herein, the terms “metric/data series” may be used. Both “metric” and “data series” describe a measurement that may be used to gauge some quantifiable component of performance of an ETL process, but “data series” may be described as a set of data for this measurement that may be used to create a graph.

A typical ETL process may utilize a range of system resources, including varying aspects of: Central Processing Unit (CPU), memory, disk Input/Output (I/O), and disk space. In addition, various metrics/data series related to the performance of the ETL process itself are of interest, including, but not limited to: total data rows processed (Total Rows); total number of rows processed on the input (Rows In); total number of rows processed on the output (Rows Out) and an indication of current performance (Rows per second). The measurements of systems resources used by the ETL process and related to the performance of the ETL process may be described as current metrics/data series for a particular measurement of an Extract, Transformation, Load (ETL) process.

In order to monitor variances in these repeating process executions, the ETL user may want to compare and analyze the ETL process execution related metrics/data series across two or more executions of a given ETL process. Moreover, the ETL user may want to carry out this comparison and analysis via a Web 2.0 based User Interface (UI) hosted on a remote computer via a client session. Analysis may be done by creating graphs of each specific metric/data series for each of the ETL process executions, so that the ETL user can see the variance in the metric/data series over time.

With traditional graphing tools, graphs can be displayed for different metrics/data series in an overlay. Graphical User Interface (GUI) buttons may be used to select/deselect metrics/data series for display in a composite (overlay) graph. The user activates a metric/data series for display in order to get an indication of the metric/data series performance.

Thus, there can be numerous metrics/data series involved when analyzing a typical ETL process execution. When large numbers of metrics/data series are presented using traditional graphing tools, the graphical view presented to the user may be congested. Similarly, adding increasing numbers of metrics/data series to a graph can result in a congested graphical view. In such congested graphical views, it may be difficult to differentiate one metrics/data series from another.

Traditional graphing tools enable simplifying the graphing view by removing metrics/data series from being included in the graph. However, once a metric/data series is removed from the graph, the user then loses a graphical view on that removed metric/data series.

SUMMARY

Provided are a computer implemented method, computer program product, and system for presenting information about multiple data series. The multiple data series are obtained. A main graphing area with a graph showing one or more of the obtained data series, an active process execution metrics area with information about the one or more obtained data series shown in the graph, and an available process execution metrics area with one or more thumbnail views of one or more of the obtained data series available for selection to be shown in the graph are displayed.

DETAILED DESCRIPTION

The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.

FIG. 1 illustrates, in a block diagram, a computer environment in accordance with certain embodiments. In FIG. 1, a client computer 100 is coupled to one or more server computers 150 a . . . 150 n (where the ellipses indicate that there may be any number of server computers). The client computer 100 includes a client application 110, which presents a graphical analysis control 120.

Each server computer 150 a . . . 150 n includes one or more extract, transform, load processes 160 a . . . 160 n and one or more applications 170 a . . . 170 n. The applications 170 a. . . 170 n may include ETL applications. Each server computer 150 a . . . 150 n may run different applications 170 a . . . 170 n, which may lead to different metrics/data series on each server computer 150 a . . . 150 n. Also, server computer 150 a . . . 150 n is coupled to a data warehouse 180 . . . 180 n (where the ellipses indicate that there may be any number of data warehouses).

In certain embodiments, the client application 110 provides a custom graphical analysis control 120, which combines a traditional main graphing area with a number of thumbnail views related to each metric/data series being monitored. In certain embodiments, the graphical analysis control 120 is a Web 2.0 UI control. The user is able to select specific metrics/data series for inclusion in the main graphing area, via the thumbnail view. There are thumbnail views visible for all available metrics. These thumbnail views show the actual profile of the live metric/data series, not a static representation, therefore, enabling the user to easily get an “at a glance” view of the profile of the comparison for each specific metric/data series, without having to add the metric/data series to the main graph. A live thumbnail view may be described as representing real-time metrics/data series data (i.e., current or dynamic data at a point in time). In certain embodiments, as the metrics change in real-time, the thumbnail views change in real-time. This will also aid the user in identifying the metrics/data series to select for detailed analysis via the main graph, as all comparative graph profiles are viewable at the same time. The graphical analysis control 120 reduces the complexity caused by “congestion” when adding multiple data series to a graphing view and will enable a large amount of comparison data to be represented within the confines of a limited dimension (e.g., where size is limited by screen real estate).

An ETL application 170 a . . . 170 n captures and maintains metrics/data series related to the execution of ETL processes 160 a . . . 160 n for presentation on-demand to the client computer 100. The client application 110 presents the graphical analysis control 120. In certain embodiments, the client computer 100 is a remote client hosting a Web 2.0 based UI, and the client application 110 is a Web 2.0 client application. In certain embodiments, the graphical analysis control 120 may be described as a multi-faceted graphing control, implemented as a custom UI control.

FIG. 2 illustrates a layout of a graphical analysis control 200 in accordance with certain embodiments. The graphical analysis control 200 includes three functional areas: a main graphing area 210, an active process execution metrics area 220, and an available process execution metrics area 230.

The main graphing area 210 shows multiple data series related to a number of user-selected ETL process execution metrics, for two or more ETL process executions. The main graphing area 210 is used for detailed comparison of the selected one or more metrics for the ETL process executions, with appropriate scale shown on the x- and y-axes.

The active process execution metrics area 220 shows a key (e.g., line style) for each current, user-selected metric/data series represented in the main graphing area 210 and shows details related to that metric/data series.

The available process execution metrics area 230 shows one or more live thumbnail views. The thumbnail views may be described as comparison graphs of each available ETL process execution metric. In certain embodiments, the thumbnail views are selectable via drag/drop gestures.

In certain embodiments, the graphical analysis control 120 instantiates with a default selection of the “Total Rows” metric/data series represented on a graph in the main graphing area 210 for comparison of ETL process executions. In certain embodiments, the user may set one or more default metrics/data series to be shown in a graph initially. The ETL user sees the graph of Total Rows metric/data series for each ETL process execution and may analyze the differences between the graph profiles.

The active process execution metrics area 220 shows details of the line style used to depict the “Total Rows” metric/data series and specific details relevant to the “Total Rows” metric/data series. The active process execution metrics area 220 displays a variable number of metrics/data series and scales to fit the available screen space.

The available process execution metrics area 230 presents to the user each of the available ETL process execution metrics/data series for two or more ETL process executions, as a comparison graph, presented as a thumbnail view. The available process execution metrics area 230 displays a variable number of metrics/data series and scales to fit the available screen space.

These thumbnail views show the actual profile of the live metric/data series, not a static representation, therefore, enabling the user to easily get an “at a glance” view of the profile of the comparison for each specific metric/data series, without having to add the metric/data series to the main graphing area 210. This will also aid the user in identifying the metrics/data series to select for detailed analysis in the main graphing area 210, as all comparative graph profiles are viewable at the same time.

The ETL user may add graphs from the available process execution metrics area 230 to the active process execution metrics area 220 for display in the main graphing area 230 for a more detailed comparison/analysis of any given metric. To avoid congestion in the main graphing area 210, previously selected metrics/data series may be removed, while the live thumbnail view for all metrics/data series are still shown in the available process execution metrics area 230. This will give the user a complete view of all available ETL process execution metrics/data series for the comparative ETL process executions, in a single custom UI control.

FIG. 3 illustrates an example graphical analysis control 300 with a selected metric/data series and live thumbnail views in accordance with certain embodiments. The graphical analysis control 300 includes three functional areas: a main graphing area 310, an active process execution metrics area 320, and an available process execution metrics area 330.

In FIG. 3, the graphical analysis control 300 shows a single metric/data series in the main graphing area 310 for the “Rows In / Second” metric/data series 334, from two comparative ETL process executions 322, 324. The ETL user can also see the comparative profiles of other metrics/data series via the live thumbnail views presented in the available process execution metrics area 230. The other metrics/data series include: “Total Rows” 332, “Rows Out / Second” 336, “CPU” 338, “Memory” 340, and “Disk Space” 342. In certain embodiments, when a metric/data series is selected from the available process execution metrics area 330, the selected metric/data series is displayed in a manner indicating the selection (e.g., the selected metric/data series is “grayed out” or shown in a light shade of gray). For the example of FIG. 3, the “Rows In / Second” metric/data series 334 may be displayed as “grayed out” in the available process execution metrics area 330.

FIG. 4 illustrates an example graphical analysis control 400 with multiple selected metrics/data series and live thumbnail views in accordance with certain embodiments. The graphical analysis control 400 includes three functional areas: a main graphing area 410, an active process execution metrics area 420, and an available process execution metrics area 430.

In FIG. 4, the graphical analysis control 400 shows two metrics/data series in the main graphing area 410 for the “Total Rows” metric/data series 432 and the “CPU” metric/data series 438, from two comparative ETL process executions 422, 424 for the “Total Rows” metric/data series 432 and two comparative ETL process executions 426, 428 for the CPU″ metric/data series 438. The ETL user can also see the comparative profiles of other metrics/data series via the live thumbnail views presented in the available process execution metrics area 230. The other metrics/data series include: “Rows In / Second” 434, “Rows Out / Second” 436, “Memory” 440, and “Disk Space” 442.

FIG. 5 illustrates, in a flow diagram, logic performed by the graphical analysis control 120 in accordance with certain embodiments. FIG. 5 is formed by FIGS. 5A and 5B. In FIG. 5, control begins at block 500 with the graphical analysis control 120 obtaining metrics/data series. In certain embodiments, the client application 110 obtains the metrics/data series from the applications 170 a . . . 170 n for use by the graphical analysis control 120.

In block 502, the graphical analysis control 120 displays or refreshes (if previously displayed) a main graphing area with a graph showing one or more metrics/data series, an active process execution metrics area with information about metrics/data series shown in the graph, and an available process execution metrics area with one or more live thumbnail views of available metrics/data series for selection. In certain embodiments, the one or more metrics/data series are default metrics/data series.

In block 504, the graphical analysis control 120 determines whether selection of an available metric/data series from the available process execution metrics area has been received. If so, processing continues to block 506, otherwise, processing continues to block 512 (FIG. 5B).

In block 506, the graphical analysis control 120 updates the graph in the main graphing area to add the selected metric/data series. One or more default and/or previously selected metrics/data series may already be shown in the graph, and the newly selected metric/data series is added to the graph in addition to the previously selected metrics/data series.

In block 508, the graphical analysis control 120 updates the active process execution metrics area to show information about the selected metric/data series.

In block 510, the graphical analysis control 120 updates the available process execution metrics area to show that the selected metric/data series has already been selected. For example, the selected metric/data series may be shown as “grayed out”. From block 510 (FIG. 5A), processing continues to block 512 (FIG. 5B).

In block 512, the graphical analysis control 120 determines whether deselection of a metric/data series from the active process execution metrics area has been received. If so, processing continues to block 514, otherwise, processing continues to block 500 (FIG. 5A) so that a “refresh” of the data series can occur.

Thus, in certain embodiments, the flow of processing of FIG. 5A and 5B will repeat/loop in order to get up-to-date data about each metric/data series, to support the live aspect of the thumbnail representations in that they may change over time (e.g. if the ETL process execution is still in progress).

Merely to enhance understanding of embodiments, FIG. 5 illustrates looping between selection, deselection, and obtaining current (i.e., live) metrics/data series however, embodiments also enable a user to terminate the looping and perform other operations.

In block 514, the graphical analysis control 120 updates the graph in the main graphing area to remove deselected metric/data series. One or more default and/or previously selected metrics/data series may already be shown in the graph, and the previously selected metrics/data series continue to be shown in the graph when the deselected metric/data series is removed.

In block 516, the graphical analysis control 120 updates the active process execution metrics area to remove information about the deselected metric/data series.

In block 518, the graphical analysis control 120 updates the available process execution metrics area to show that the deselected metric/data series is available for selection. For example, if the metric/data series had been grayed out, the deselected metric/data series is shown without the graying (e.g., shown as originally displayed at the time of selection to be included in the graph). From block 518 (FIG. 5B), processing continues to block 500 (FIG. 5A) so that a “refresh” of the data series can occur.

Thus, the graphical analysis control 120 shows live data in thumbnail views. The graphical analysis control 120 presents information for multiple, varying metrics/data series in graphs. The graphical analysis control 120 creates thumbnail views for each metric, and each of the thumbnail views illustrates the actual metric/data series performance of a particular metric/data series as a graph. These thumbnail views may be selected and deselected for display on the composite (overlay) graph. In this way, the user is able to gain insight into each metric/data series before (or without) the metric/data series being displayed on the composite (overlay) graph.

The graphical analysis control 120 enables the ETL user to have visibility of the comparison graph profile for each metric/data series and to see the data for all metrics/data series at any one time. The graphical analysis control 120 presents a large number of different data series related to numerous metrics, for two or more ETL process executions, in an understandable way within a UI frame of limited visible dimension (e.g., where size is limited by screen real estate). The graphical analysis control 120 enables a view on all metrics/data series at all times.

The graphical analysis control 120 provides simplified graphical analysis of multiple data series/ETL process runtime metrics. The graphical analysis control 120 combines a traditional main graphing area with a number of thumbnail views related to each metric/data series. The graphical analysis control 120 enables selecting/deselecting specific metrics/data series for inclusion in the main graphing area via the thumbnail view (where the thumbnail views are visible for all available metrics/data series). The graphical analysis control 120 also enables identifying the metrics/data series to select for detailed analysis via the main graphing area.
